Gib-BURNER.V

SPECIFICATION forming part of Letters Patent N o. 731,078, dated June 16, 1903.

Application filed February 24, 190.2. Serial No. 95,240. (No model.)

To @ZZ whom, it may concern: p

Be it known that I, ROBERT G. SPEER, a citizen of the United States of America, and a resident of St. Louis, State of Missouri, have invented certain new and useful .Improvements in Oil-Burners, of which the following is a specification.

The present invention relates to thattype of oil-burners in which the hydrocarbon-oil ro is fed in a gradual manner into a pan arranged within the lire-chamber of a cookingrange or the like to he consumed therein; and the present improvement has for its object to provide a simple and efficient construction of I5 parts in which the combustion of the oil is attained in a safe and eective manner and the clogging up ot' the inlet-pipe as well as local combustion at the outlet-orifice of such inlet-pipe are avoided, all as will hereinafter 2o more fully appear, and be more particularly pointed out in the claims.

In thevaccompanying drawings, illustrative of the present invention, Figure l is a fragmentary longitudinal sectional elevation ofV an ordinary cooking-range, illustrating the general arrangement of the present invention; Fig. 2, a transverse section at line .fr Qc,

Fig. l; Fig. 3, an enlarged detail section of the combined oil and air inlet bushing or noz- 3o zle of the present invention.

Similar numerals of reference indicate like parts in the different views.

Referring to the drawings, l represents the fire box or chamber of stove or range of any usual construction; 2, the usual grate-bars, which in the construction shown in the drawings constitu te the support for the pan-burner of the present invention; 3, an open-topped pan or vessel resting upon the fire-grate 2 and 4o adapted to contain a loose filling of sand, lirebrick fragments, or analogous material, as usual in the present type of oil-burners, and which pan is preferably of a size smaller than the tire or combustion chamber l, so that airpassages are formed at the sides of the pan,

ples attached to the bottom of the pan 3 and adapted to afford an additional supply of air for use in the combustion of the fuel and by their arrangement intermediate the length and width of the pan are adapted to afford a more efficient introduction of the air-supply into intimate relation with the burning fuel than would be the case were dependence placed wholly upon the side passages hereto- 6o fore described; 5, an inclined chute extending from the central portion ol the pan to one side of the pan 3 to a point adjacent to one end of such pan and which chute is provided with marginal fianges, as shown, or otherlike l provisions, so as to be adapted to receive the oil from the oil-supply pipe, arranged as hereinafter described, and conduct the saule t0 the center of the pan and from which point the oil is adapted to evenly distribute itself 7o by gravity to all parts of the pan vand the loose filling of the same to effect a uniform combustion throughout the com bustion-chamber.

6 is the oil-supply orinlet pipe, provided 75 with the usual controlling-valve 7 and connected in any usual manner to the storagetank, from which the supply of oil used with the present burner is taken.

8 is a lid fitting one of the pot-holesin the top 8o wall or deck of the range and to which the outlet end of the oil-supply pipe 6 is connected.

As so arranged an vapplication and a subse-- e quent removal of the present 'invention to a range or stove is rendered very easy and con- 85 venient, the lid 8 taking the place of an ordinarystove-lid in the one case and vice versa in the other case, and in consequence a range can be changed from a coal-burner to an oil-burner and back again to a coal-burner when so de- 9o sired in a rapid,convenient,and inexpensive 9 is a bushing, Which'in the preferred form of the present invention constitutes the connection between the lid 8 and the end of oil- 95 supply tube 6, and to such endthe said bushing will have a central screw-threaded bore, into which the end of such pipe is screwed, and the periphery of the bushing will be screw-threaded and in turn screwed into a ico screw-threaded orifice in the lid S, as illustrated in Fig. o.

lO is an annular chamber formed in the bushing 9, concentric with the bore thereof which receives the inlet-pipe 6, as above described. At its top such chamber communi- Cates with a series of passages 11, extending through the top portion of the bushing, while its lower end is open. With such construction the natural draft of the range, duc., is adapted to cause an inward or downward flow of air through the chamber lO and which air discharging as an annular jet around the oil dropping from the inlet-pipe 6 onto the chute 5 is adapted in-a "ery perfect manner to prevent a local combustion immediately at the point of exit of the oil from said pipe and the consequent clogging of the same by the formation at such point of a carbonaceous cake, which will occur where some provision like the present is not provided.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Paten t, is-

1. A range or stove comprising a combustion-chamber, a usual coal-supporting grate, a lid adapted to tit a pot-opening of the range or stove, an oil-supply pipe attached to said lid, an oil-burning pan fitted to extend over and rest upon the coal-supporting grate, and a laterally-deflecting open chute or conduit extending continuously from substantially the central portion of the oil-burning pan toV a point above and to one side thereof beneath the oil-supply pipe to distribute the oil evenly over the oil-burning panand effect a uniform combustion throughout thecombustion-chamber.

2. A range or stove comprising a combustion-chamber, a usual coal-supporting grate, a lid adapted to fit a pot-opening of the range lor stove, an oil-supply pipe attached to said Y lid, an oil-burning pan tted to extend over andA rest upon the coal-supporting grate and having a series of tubular nipples attached to the bottom of the pan and constituting supplemental air-passages, and a laterally-de fleeting open chute or conduit extending from substantially the central portion of the oilburning pan continuously to a point above and to one side thereof beneath the oil-supply pipe to distribute the oil evenly over the oil-burning pan and eect a uniform combustion throughout the combustion-chamber.

3. An oil-burner for ranges and the like, comprising in combination, a lid adapted to fit a pot-opening of the range, an oil-supply pipe centrally attached to said lid, the lid being provided with a series of orifices surrounding the centrally-disposed supply-pipe,

an oil-burning pan detached from and arranged beneath said oil-supply pipe, and a laterally-deiiected open chute arranged intermediate of the oil-supply pipe and the panburner and extending to the latter, substantially as set forth.

4. An oil-burner for ranges and the like, comprising lin combination, a lid adapted to fit a pot-opening of therange, an oil-supply pipe, an intermediate bushing forming a connection between the supply-pipe and the lid and provided with a centrally-disposed oil# supply pipe and an annular chamber and a series of orifices surrounding the supplypipe, an oil-burning pan detached from and arranged beneath the oil-supply pipe within the combustion-chamber, and an open chute Wholly Within the combustion-chamber and extending from the oil-burning pan to a point beneath the lid, substantially as set forth.
